In particular, a unit-type building that is composed of box-shaped building units has the characteristics that the work on the construction site is significantly reduced and the construction period is extremely short because most of the interior and exterior of the building unit are done in the factory. ing. Such a box-shaped building unit is provided with a hexahedral skeleton in which the upper and lower ends of columns at four corners are connected by upper and lower beams, respectively. As an example of a building unit, FIG. 4 shows an entrance building unit 40 arranged at the entrance of the building.

The entrance building unit 40 is a building unit in which a surface 1 including the short side on the left side of the drawing is opened for entrance. The upper ends of the pillars 2 at the four corners of the entrance building unit 40 are connected to each other by upper long side beams 3A and upper short side beams 3B. Pillar 2
Except for the lower ends on both sides of the surface 1, the lower ends are connected to each other by the lower long-side beam 4A and the lower short-side beam 4B. A stud 5 is provided on the right side of the surface 2 on the left side of the pillar 2. The upper end of the stud 5 is connected to the upper short side beam 3B on the surface 1 side. Stud 5
The lower end of is connected to the short lower beam 6A joined to the lower end of the pillar 2 described above. A beam connecting the lower end of the pillar 2 and the lower end of the stud 5 on the right side of the surface 1 in the drawing is omitted. Only when the entrance building unit 40 is transported, the lower ends of the pillars 2 on the right side of the surface 1 and the lower ends of the studs 5 are connected to each other by a temporary beam 6B so that no space is left between them.

On the floor of such an entrance building unit 40, an entrance frame 41 corresponding to the exclusive entrance foundation 11 provided at the entrance of the foundation 10 is provided. Entrance foundation 11
Is the dirt floor edge base 13 along the inner edge of the dirt floor 12 that serves as the entrance floor, and the dirt floor edge base along the side edge of the dirt floor 12.
It is a cloth foundation with 14 and 15. The entrance frame 41 is
In addition to being arranged according to the soil edge base 13, the soil edge frame 42 bridged between the lower long-side beams 4A and the soil side edge foundation 15 on the left side of the drawing , The soil side edge frame 43 spanned between the short lower beam 6A and the soil edge frame 42, and is arranged according to the mounting position of the entrance sash, and is also hung between the lower surface of the lower long side beam 4A. The sash receiving frame 44 passed over. The lower ends of a pair of studs 7 for attaching the entrance sash are joined to the sash receiving frame 44. The upper end of the stud 7 is joined to the entrance girder 8 spanned between the upper long-side beams 3A.
